EYE SHADE Filed May 31, 1947 /I/IJJXQ) FY INVENTOR.

Patented Dec. 13, 1949 UNITED STATES PATENT OFFICE 1 Claim. 1

The invention relates to eye-shades, and more specifically it relates toa new type of eye-shade as described in my patent application Ser. No.746,571.

The new eye-shade as described in said patent application ischaracterized by an elongated mechanical bar across the face in the zoneof the eye-brows. Its main characteristics are a rollating nose-restfitting into the recess of the bones between the brow-zone of the skulland the nosebone, and pivots for holding means, said pivots beingcoaxial with the axis of a mathematical cylinder of which the curvednose-rest is a segment.

When producing such an eye-shade in plastics, it is important to avoidthick walls. In this respect the cited patent application had shown amodification, in which the bar was of tubular structure.

The present application shows a modification, in which the bar is a fiatplate, which is so to say the longitudinal center slice of amathematical cylinder. In the middle of said plate, said rollating noserest is retained, forming-as in the other two modifications of thecopending patent application-a segment of the same mathematicalcylinder. At each end of said plate a pivot for the holding means isprovided, said two pivots being coaxial with the axis of saidmathematical cylinder.

The invention is illustrated, by way of example, in the Figures 1-7inclusive of the accompanying drawings.

Fig. 1 shows a side view of a person wearing the eye-shade.

Fig. 2 shows a front view of the person shown in Fig. 1.

Fig. 3 is a cross section along the plane I2-l2 indicated in Fig. 2.

Fig. 4 is a cross section along the plane l3-I3 indicated in Fig. 3.

Fig. 5 is a top view of the plate.

Fig. 6 is a. perspective view of Fig. 5.

Fig. 7 is a cross section, illustrating a. detail of Fig. 3. It showsthat mathematically the curve of the actually rollating contactsurfaceand not the curve of such side guides as may be provided againstskidding off the nose and as shown in the Figures 1 to 6 inclusive-iscomputed on to arrange the pivots coaxially.

Fig. 3 shows in dotted lines a tilted position of the shade. Due to thecoaxial arrangements of the pivots, there is no eccentric lever effectwhen the shade is tilted, rollating on its nose rest. The thrust againstthe nose remains the same.

Having now described the nature of my invention and having shown byexamples the manner in which it may be performed, I claim as myinvention:

An eye shade of the type described including an elongated shade memberand a, rollating nose rest in which the eyes are shaded by saidelongated shade member arranged across the face in the brow-zone and inwhich two pivots for holding means, one pivot at each side of saidelongated shade member, are coaxial with said rollating nose rest, saidnose rest being geometrically a segment of a cylinder; comprising ashade element which, except for the nose rest, is a longitudinal sliceof said geometrical cylinder.
